Suppressing capture of lexical regex with <.regex-name> doesn't work - works with <&regex-name>

[ronaldxs]

The Problem

$ perl6 -e 'my token t { t }; say so "t" ~~ /<.t>/'
No such method 't' for invocant of type 'Match'.

Update: it looks like this is a doc issue. If I don't hear back in a day or so I will move to doc ...

Expected Behavior

The Subrules section of the Regexes doc essentially suggests that capture suppression with <. should work on a lexical token but it does not.

Update: it looks like a doc error:
In roast S05-interpolation/lexicals.t#L10 it is done with my token abc {}; 'foo abc def' ~~ / <&abc> /

Steps to Reproduce

my regex line { \N*\n }
if "abc\ndef" ~~ /<line> def/ {
    say "First line: ", $<line>.chomp;      # OUTPUT: «First line: abc␤»
}

grammar G {
    regex g-line { \N*\n }
    regex line-def-cap { <g-line> def }
    regex line-def-no-cap { <.g-line> def }
}
say G.parse("abc\ndef", :rule('line-def-cap'));
say G.parse("abc\ndef", :rule('line-def-no-cap'));

# works ^ above but not \/ below
if "abc\ndef" ~~ /<.line> def/ {
    say "matched wo capture";
}

Environment

• Operating system:
  Description: Ubuntu 14.04.5 LTS
  Codename: trusty

• Compiler version (perl6 -v):
  This is Rakudo version 2018.05 built on MoarVM version 2018.05
  implementing Perl 6.c.

[jnthn]

Can conform that <.foo> is meant to always be a method call without capturing, and <&foo> always a lexical call without capturing.
